I work in a steel factory. In one of the premises of the workshop there is a repair, which is done by guests from Central Asia. In order to get into that room, you need to pass by the oven with a working electrical arc. Our staff with a cardiostimulator always runs very sharply past this oven. electromagnetic fields are harmful. And the gastarbayters did not understand why he ran so far past the oven. But in any case, they also started to be afraid and tried to run past her faster. They thought the devil lived there.
